Qualified Tax Notice

Concurrent with this announcement we are providing qualified notice to brokers and nominees that hold MPLX units on behalf of non-U.S. investors under Treasury Regulation Section 1.1446-4(b) and (d) and Treasury Regulation Section 1.1446(f)-4(c)(2)(iii). Brokers and nominees should treat one hundred percent (100%) of the Partnership's distributions to non-U.S. investors as being attributable to income that is effectively connected with a United States trade or business. In addition, brokers and nominees should treat one hundred percent (100%) of the distribution as being in excess of cumulative net income for purposes of determining the amount to withhold. Accordingly, the Partnership's distributions to non-U.S. investors are subject to federal income tax withholding at the highest applicable effective tax rate. Nominees, and not MPLX, are treated as the withholding agents responsible for withholding on the distributions received by them on behalf of non-U.S. investors.
